Water forms according to the equation below: 2h2(g) + o2(g) jpg 2h2o(g) hrxn = -483.64 kj how much energy is released during the formation of 1 mol h2o(g)? kj

Answer : The amount of energy released is, -241.82 KJ

Explanation : Given,

The balanced chemical reaction is,

From this we conclude that,

As, 2 moles of released amount of energy = -483.64 KJ

So, 1 mole of released amount of energy =

Therefore, the amount of energy released is, -241.82 KJ

the answer would be b i believe

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
